What does the order of except branches refer to in exception handling?

• A. Exceptions caught in any order
• B. Exceptions completed randomly
• C. Completed sequentially
• D. Exceptions ignored

Answer: (C)

The order of except branches in exception handling refers to how Python processes multiple except statements when catching exceptions. In Python, when an exception occurs, the interpreter searches through the except blocks in the order they are defined and matches the exception type to the corresponding except block.

If the exception matches the first except statement, that block is executed, and the rest of the except blocks are skipped. This means that the handling of exceptions is done sequentially: Python evaluates the except clauses one by one, from top to bottom. Therefore, placing more specific exceptions before more general ones is important to ensure that the right exception is caught and handled as intended.

This sequential processing ensures that if a specific exception type is raised, the corresponding block that handles this specific type of exception is executed first, allowing for precise control over exception handling.
